<p>A multiple access communications system for use between a base (A) and a plurality of substations (B1 to Bn) with a first channel (C1) for transmission of data from the base to the substations and a second channel (C2) for transmission of data from the substations to the base, the system arranging substations and prospective substations (B1 to Bn) into a plurality of groups (1 to k), assigning each of a plurality of slots (1 to t) in the second channel (C2) to a particular group (1 to k), informing the substations (B1 to Bn) via the first channel (C1) of the number of substations in each group (1 to k), each substation (B1 to Bn) analyzing the numbers (u1 to uk) of substations in each of the groups (1 to k) and determining which group (1 to k) to associate itself with in order to next communicate with the base (A) in the slot or slots (t) assigned to that group.</p> |
